Not really how that works. Also earths core is being heated from nuclear decay and tidal effects. It’s getting 10’s or TW worth of heat until the sun expands and eats the earth. https://en.wikipedia.org/wiki/Earth's_internal_heat_budget

The world's total energy consumption (most of which is fossil fuels) is currently estimated at 620 exajoules, or 17TWh / year.

Assuming zero growth in energy consumption (hello AI), extracting even half of that seems like it would be consequential.

10 TW * 1 year = 8,760 TWh / year. The current rate of energy production is ~42TW and slowly dropping over billions of years, so even after efficiency losses gathering 1% of what’s produced is several times current energy consumption.

I believe this is off by 5 or 6 orders of magnitude.

Looks like it's more like 200,000Twh / Yr

Thanks for that wikipedia link, it's fascinating!

I think they meant that as a joke.
